On an otherwise quiet night there is a startling knock at the door. Andrew Tucker answers the door to find an old friend whom he hasn't seen in years. The disheveled and absent friend comes to him with one request: "I need you to come with me but, I can't tell you where we're going." Andrew takes a chance but learns that every answer brings more questions. Nothing good ever comes knocking after midnight and Andrew's nightmare asks how far you would go to help a friend.

The US military is running a test for a special type of radio transmitter, to be used to communicate with submarines, in a deep system of underground caves in Central America. When the signal from one of the transmitters suddenly disappears, a team of soldiers led by Major Elbert Stevens and cave specialists led by Rupert 'Wolf' Wolfsen including scientist Leslie Peterson are sent in to find out what happened. Exploring deep underground, they stumble upon a tribe of albino cave-dwellers who have apparently been isolated from the rest of the world for thousands of years. The cave-dwellers are hurt by radio frequencies and are able to see in infra-red frequencies, tracking the explorers by their body heat.
